All of this is why I've long thought LOGAN'S RUN is an ideal candidate for a remake. The original has some neat concepts and visuals, and is fondly remembered by a generation of fans, but it hasn't aged well and was never an untouchable masterpiece that can never be surpassed. There's room for improvement here, and you wouldn't exactly be treading on sacred ground by doing an updated take on the material.
I don't disagree, but I think there's a fundamental issue with the story's message.
I mean, what was the point of it all? For 'THX-1138' it was about the dehumanising effect of a souless bureaucracy. For 'Brave New World' it was more about questions on what it means to be happy and human and the role of pain and suffering in the same.
'Logan's Run' seems to borrow heavily from these and others, but it's mostly surface level only and never really lands on any real point beyond "stick it to the man!"
Furthermore, who is Logan really? Was it just random chance that landed him with that assignment? Or was it his persistent (if mostly idle) questioning of the status quo? At what point did he decide that he really was a runner after all and where did his sudden onset of social conscience come from that prompted him to go back and stage a one man cultural revolution. For a title character that's in almost every scene and TONS of dialogue, we never really know what's going on in his head or what's really motivating him.
I suspect the combination of this lack of a solid hook and fully formed protagonist is at least partly why there's yet to be a remake. I can imagine there's a small stack of attempted drafts over the years with various takes on the subject matter, but nothing's really connected to a degree to overcome the dated, silly image the original movie has.
These days, remakes mostly happen to bank on nostalgia rather than to polish up an old gem, so the prospect of remaking a relatively obscure IP probably isn't all that appealing to the money people.
OK, not "obscure" exactly, but it's not a "classic" either. It's in a weird nostalgic no man's land in that it's almost *too* well remembered, but for the wrong reasons.
There's also what I call the "John Carter Effect". Where the later imitators are more well known than the inspiration, so any attempt at adapting it is going to look derivative because others have done this better already. To give an example off the top of my head; 'Equilibrium' was pretty much 'Logan's Run' meets 'Fahrenheit 451' by way of 'The Matrix'.
